The effects of duration of hemodialysis on the parameters of central and peripheral hemodynamics in patients with end-stage renal disease

Aim

To assess the effect of duration of treatment with hemodialysis (HD) on parameters of peripheral and central hemodynamics during the 44-h intradialytic period.

Material and methods

We performed 44-h ambulatory blood pressure monitoring (ABPM) during the interdialytic period in 68 adults with end-stage renal disease (ESRD) on maintenance HD. Blood pressure (BP) was measured in the brachial artery and aorta using a validated oscillometric device and was analyzed according to the HD duration: 3 to 48 months, 49 to 84 months or more than 84 months.

Conclusion

In patients with ESRD, a longer duration of treatment with HD was associated with an increase in the peripheral and central SBP (44-h, for Day 1 to Day 2 of intradialytic days 1 and 2) and central DBP. The greatest increase of BP from the first to the second intradialytic day was observed in patients with duration of treatment of more than 84 months.
